Does someone know if our WK2 EcoDiesel is equipped with an additional exhaust valve that will cause a backpression in the cylinder?
According to this YouTube video, there are 2 majors technologies to decelerate a diesel motor by compression:
1) Add an additional exhaust valve
2) Use Jig braking (opening cylinder's exhaust valve during compression phase to let air out)
I think our WK2 would have the first technology. I personally dislike compression performance. There is not enough to my taste.
